Hmm, well that they already do in 2ch formats (compress more to get it louder). In ac3 case I rather think it is ignorance.
As the commecial are not always ac3(are they at all?), the
In case of Pro7, Sat.1, ZDF you have one seperate mpa and ac3 track and on the ac3 track you only have ac3 transmitted - either in 5.1 or 2.0.
"dialog normalization value" must be changed on evey break.
In a perfect worls, yes. :-) But usually ads are eual loud, so that is not the problem.
Add-dropping software would be lucky to have such an exact signal to detect "commericals" ends and beginns!
You already have if you watch a 5.1 movie: Commercials on ac3 track are to 99% 2.0 (except one Yamaha ad for av receivers, which is 5.1 - guess why).
in your -very- silent listning room, so you have to gerate 120DB(A) in the peaks to get 100dB range!
Yes, true. but I think loud low frequs are not that bad (except for the neighbors ;-) than eg 1kHz at 120db... I never measured the loudness I listen too, but I am not listening movies at soft volumes. ;-)
dynamic range in the long term. Be cautious! (Have a look for "Tinitus" etc. in the Web).
Oh, well, I already have but because of stress...(it comes and goes...)
